present a clean regulated DC supply to the sensor. The monitoring equipment should likewise be

immune from the effects of electromagnetic disturbances and not impart disruptive signals on the

connections to the sensor.

3.7.2 Cable Type

Due to the small size of the sensors they are unlikely to be directly affected by radiated RF

energy. Any RF energy that gets into the circuits will probably enter via the interconnecting cable.

To minimize the effect of nearby circuits and events, it is necessary to use screened cable

between the sensors and power supply/monitoring equipment. Failure to do so will invalidate the

EMC tests conducted by "Druck".

The choice of cable type should reflect the environment through which it is going to run. Screened

cable should always be used where electrical noise is present. Good cabling practice will be

reflected in signal quality.

For the screening of the cable to be effective, it is essential that the screen or drain conductor is

permanently bonded to earth (ground). This should take place at the monitoring end of the cable

as close to the power supply as practical. Protection should be afforded to any unscreened

section of cable or circuit by means of a screened enclosure. Take care not to create ground

loops.

WARNING

environment. In the event of a fault:

•

Establish if the pressure sensor is mounted, sealed, connected and programmed correctly

as instructed.

•

Contact the manufacturer for further advice on fault elimination.

•

For persistent faults, safely remove the equipment from service. Refer to Section 3.6 for

returned goods procedure.
